Other mistake: When the waiter informs Taylor's ex that she has a phone call, he says "Call for you, Miss Russo" which is the character's real last name.
Suggested correction: She says "Ms. Weslin, there's a telephone call for you." Weslin is Lynn's last name.
Suggested correction: Lynn isn't Taylor's ex; they were never married. The waiter is a woman. That's not what she says. She doesn't call Lynn by the actor's name.
Other mistake: Roger says to Jake that he's going to be a free agent next year, which he's excited about and why he doesn't want to risk injury, but then when he learns of the owner's plan and that he'll be given his release next year, which is the same as free agency, he's upset. Plus you can't be given your release when your contract ends, which it must be if he thought he was going to be a free agent.
Suggested correction: Roger says he'll be a free agent after the next season, not the current season. Depending on the terms of his contract, he could be optioned to the minors or designated for assignment, which could reduce his value on the market when he does become a free agent. This plot point is actually rendered moot a bit in the sequel when he retires, but does come into play as he can activate himself as he's still under contract with the Indians.
